Abstract

A two-piece harness retainer is adapted to hold a pair of harness straps in side-by-side relation. A tether is provided to limit pivoting movement of a pivotable latch arm included in one of the pieces included in the harness retainer.

Description

BACKGROUND AND SUMMARY

The present invention relates to harness retainers and, in particular to a harness retainer for use with a juvenile vehicle seat. More particularly, the present disclosure relates to a snap-together, two-piece harness retainer.

Harness retainers hold shoulder straps together so that straps lie properly on a person wearing a harness assembly including the shoulder straps. Typically, harness assemblies are used to restrain a child seated in a juvenile vehicle seat as a safety precaution.

In accordance with the present disclosure, a two-piece harness retainer includes a latch unit adapted to be coupled to a first shoulder strap in a harness assembly and a latch retainer adapted to be coupled to a second shoulder strap in the harness assembly. A blade in the latch unit is sized to fit into a blade receiver formed in the latch retainer to cause a button in the blade to fit into a button receiver formed in the latch retainer so as to fasten the latch unit to the latch retainers A tether is provided in the blade to limit pivotable movement of a latch arm included in the blade and configured to carry the button.

Additional features of the disclosure will become apparent to those skilled in the art upon consideration of the following detailed description of preferred embodiments exemplifying the best mode of carrying out the disclosure as presently perceived.

DETAILED DESCRIPTION OF THE DRAWINGS

As suggested in FIGS. 1 and 2, a two-piece harness retainer 10 is used to hold first and

second straps

12, 14 in a harness assembly 16 in side-by-side relation at a point adjacent to the upper body of a child 18 seated in a juvenile vehicle seat 20. Harness retainer 10 includes a latch unit 21 and a latch retainer 22 configured to fasten to latch unit 21 as shown in FIGS. 2 and 3. Latch unit 21 includes a pivotable latch arm 24 that is tethered by tether 26 as shown, for example, in FIGS. 5-7 to limit the range of pivotable movement of latch arm 24 about a pivot axis 28 as shown, for example, in FIG. 8.

As shown, in FIGS. 1 and 2, juvenile vehicle seat 20 includes seat bottom 30 and seat back 32. Illustratively, harness assembly 16 also includes a crotch strap 34,

lower straps

36, 38, and a buckle assembly 40. It is within the scope of this disclosure to use two-piece harness retainer 10 with a wide variety of harness assemblies.

Harness retainer

10 includes a latch unit 21 and a separate latch retainer 22. Preferably, each of

components

21, 22 is a molded plastic part and adapted for use with a wide variety of harnesses including a child-restraint harness of the type used with juvenile vehicle seats.

Latch unit

21 is shown best in FIGS. 5 and 7 and includes a base 42 and a blade 44 coupled to base 42. Base 42 is formed to include a first strap receiver 46 that is adapted to receive first strap 12 as shown, for example, in FIGS. 1 and 2. In the illustrated embodiment, first strap receiver 46 is defined by a pair of spaced-apart strap-

receiving slots

47, 48.

Latch retainer

22 is shown in FIGS. 3, 4, and 7 and is formed to include a blade receiver 50 and a button receiver 52 in communication with blade receiver 50. As shown in FIG. 7, blade receiver 50 is formed in latch retainer 22 to receive blade 44 of latch unit 21 when latch unit 21 is coupled to latch retainer 22. Button receiver 52 is formed in latch retainer 22 to receive a button 54 included in blade 44 when blade 44 is inserted fully into blade receiver 50 to couple latch unit 21 to latch retainer 22.

Latch retainer

22 is formed to include a second strap receiver 56 that is adapted to receive second strap 14 as shown, for example, in FIGS. 1 and 2. In the illustrated embodiment, second strap receiver 36 is defined by a pair of spaced-apart strap-receiving

slots

57, 58.

As shown best in FIGS. 4-6, blade 44 includes a latch carrier 60 coupled to base 42 and formed to include a latch-receiving space 62. Blade 44 also includes pivotable latch arm 24, latch button 54, and tether 26. Pivotable latch arm 24 includes root end 64 cantilevered (e.g., as by a “living hinge”) to latch carrier 60 to position latch arm 24 for pivotable movement in latch-receiving space 62. Latch arm 24 also includes a free end 66 located in spaced-apart relation to root end 64. Latch button 54 is coupled to latch arm 24 to pivot therewith as suggested in FIG. 8.

Tether 26 has a first end coupled to free end 66 of latch arm 24 and an opposite second end coupled to another portion of latch unit 21 (e.g., base 42) to limit pivotable movement of latch arm 24 relative to latch carrier 60 as suggested, for example, in FIG. 8. Tether 26 is provided by an elongated, corrugated, extensible ribbon as shown, for example, in FIGS. 5-8.

Latch carrier

60 includes a U-shaped frame 70 having a first leg 71, second leg 72, and cross member 73. First leg 71 lies along a first side 74 of pivotable latch arm 24. Second leg 72 lies along a second side 75 of pivotable latch arm 24. Cross member 73 interconnects first and

second legs

71, 72 and supports root end 64 of pivotable latch arm 24.

Latch carrier

60 further includes a first frame support 76 coupled at one end thereof to first leg 71 and at an opposite end thereof to base 42. Latch carrier 60 also includes a second frame support 77 coupled at one end thereof to second leg 72 and at an opposite end thereof to base 42. First and second frame supports 76, 77 are arranged to lie in spaced-apart relation to one another to define a tether channel 27 therebetween. Tether 26 is positioned to lie in tether channel 27 as suggested in FIGS. 4-6. Tether channel 27 is arranged to communicate with latch-receiving space 62.

Tether 26 has a first side edge 78 positioned to lie in confronting and spaced-apart relation to first frame support 76 as suggested in FIGS. 4 and 5. Tether 26 also has a second side edge 79 positioned to lie in confronting and spaced-apart relating to second flame support 77 as suggested in FIGS. 4 and 5. In the illustrated embodiment, tether 26 has a first straight portion 80 coupled to free end 60 of pivotable latch arm 24 and a second straight portion 82 coupled to base 42. Tether 26 also includes a serpentine portion 84 arranged to interconnect first and second

straight portions

80, 82 and to extend in a direction perpendicular to laterally extending pivot axis 28. As shown best in FIG. 4, pivotable latch arm 24 and tether 26 cooperate to define a T-shaped member.

Latch arm

24 is coupled to latch carrier 60 to provide means for moving button 54 into button receiver 52 following insertion of blade 44 into blade receiver 50 to retain latch unit 21 in a fixed position relative to latch retainer 22. Tether 26 is configured to provide means for tethering latch arm 24 to limit movement of latch arm 24 relative to latch carrier in an “up” direction 90 and a “down” direction 92 as suggested in FIG. 8.

To disconnect latch retainer 22 from latch unit 21 from the interlocked or latched position shown in FIG. 3, it is necessary only to push latch button 54 to cause latch button 54 to leave button receiver 52 and move into blade receiver 50. Then latch retainer 21 can be moved away to disengage latch retainer 22 to assume the separated position shown in FIG. 4.
